Question

Find out number of gram atoms present in 8grams of oxygen with explanation using formula​

Answer 1

Answer:

Don't think about any formula just apply unitary method

We know gram atomic mass of an element is equal to one mole

So, 16g oxygen(atom) =1mole of oxygen atom otherwise 32g(if molecule o2)

1g oxygen = 1/16 moles

SO, 8g oxygen = 1/16*8 = 8/16 = 1/2 = 0.5 moles
